Impossible to burn bootloader into chineese MEGA 2560 board using Esplora board

Dear all.
I’m triing to use Esplora board as Arduino ISP support to burn bootloader into Chineese MEGA 2560 board.
I use Arduino ISP example but, impossible to burn bootloader using both configuration (esplora → MEGA2560 ICSP port and esplora → MEGA2560 (50,51,52 ports)), as I get an error:

avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override this check.
Could you please provide the remedy for it?

I use a capacitor between RST and GND.
Thanks for your support.
